Any ideas why this doesnt work?

I made a script, which works while testing through studio, but when I get in the actual game, it doesn't. Any ideas?

script.Parent.MouseButton1Click:connect(function()
	local Level1 = script.Parent
	
	if Level1.Visible == true then
		game:GetService("TeleportService"):Teleport(284418914, player)		
	end	
	
end)
